Abstract: In this paper, the population dynamics in the process of the progressing succession of the forest vegetations in the Maxian Mountains Forest Region is studied by mathematical analytical methods. The typical and particular pattern of the progressing succession of the vegetations can be divided into the following four stages: stage of shrub, stage of small leaf broadleaf, stage of mixed forest and stage of coniferous forest. Mathematical models of succession laws are also established in this paper.Finally, we put forward the proposals of artificial regeneration and tending in this forest region.
